JAMES R. MOWANE, OF BIRMINGHAM, ALABAMA.

MULTIPLE-CORE-BARTURNING DEVICE.

Tovfal whom it may concern.'

Be it known that` I, JAMES R. MCVANE, a citizen of the United States, residing at Birmingham, in thecounty of Jefferson and State of Alabama, have invented a new and useful Multiple-Core-Bar-Turning Device, of which the following is a specification.

The invention'relates to a multiple core bar turning device.

The object of the present invention is to provide a simple, strong and efficient lnultif ple core bar turning device, adapted to support a plurality "of core bars and designed to receive the same in a heated condition immediately after the core bars have been pulledfrom the pipes, and capable of enabling the core bars to be readilyprotated while the iirst coating of skilly is applied to them by hand.

A further object of the invention is to provide a device of this character, adapted to enable core bars to be quickly placed in and removed from the supporting bearings, and capable of enabling the supported core barsto bereadily connected with and dis- Connected from gearing for imparting rotary motion to the core bars.

It is also an object of the invention to provide convenient operable actuating gearing, located beyond the core bars and out of the way of the skilly when the same is thrown upon the core bars in applying the irst coating thereto.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafterfully described, illust-rated in the accompanying drawings, and pointed out in the claims heretoappended.

Serial No. 627,596.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

The specification and drawings are a disclosure of one embodiment of the invention, while the claims define the actual scope of the invention.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the multiple core bar turning device is designed to receive core bars 1 in a heated condition, after they have been pulled from the pipes, and it is adapted to simultaneously rotate a plurality of core bars While the first coating of skilly7 is being applied thereto. The word skilly is an arbitrary word and is used to convey the idea of any mixture, that will adhere when thrown on a hot core bar and dry sufficiently to hold the second coating of mud or loam, and that it contains a suHicient quantity of combustible material, such as manure, chopped hay, saw dust or the like, to burn out when the heat of the cast ma terial comes on the core and subsequently release the core bar.

The multiple core bar turner is designed primarily for use in the foundry plant, forming the subject-matter of a co-pending application, filed Mar. 30, 1911, Serial No. 618,015, but it may be used for supporting and rotating core bars while they are being treated in any other manner.

The core bars are supported in a'horizontal position by spaced bearings 2, each consisting preferably of a horizontal base 3 `and a vert-ical web 4, provided in its upper edge with bearing recesses 5. The spaced bearings are mounted upon suitable supports 6, being secured to the same by bolts 7, or other suitable fastening devices, which pierce the horizontal base 3. The core bars, which rest in the bearing recesses 5, are provided at one end with an annular groove 8, receiving the vertical web of the contiguous bearing 2 and forming inner and outer shoulders, arranged to engage the inner and outer faces of the, web 4' of such bearing to prevent longitudinal movement and displacement of the core bars.

The core bars are connected at one end v with a horizontal series of meshing pinions 9, provided at opposite sides with extended hub portions 10, journaled in bearing recesses 11 of spaced pedestals 12, which are tained in the 'bearing recesses 11 by a cap 14. The pedestals, which may be constructed in any suitable manner, are preferably pro vided with marginal flanges and vertical reinforcing or bracing webs 15, -and the bot tom marginal flanges 1.6 are secured by bolts 17, or 'other suitable fastening means to the upper face of the support 13. The cap 14, which is mounted upon the pedestals, is arched transversely over the space between the same, and it is provided with laterally extending ianges or portions 18, which are secured to the pedestals-by bolts I9. The laterally extending flanges or portions of the cap are curved o form bearing recesses 20 to'complete the bearings of the extended hub portions of the pinions or gears 9. 'llhe ends ofthe cap are curved downward partially around the end gears of the series and the cap,l and the pedestals support and incase the gears toprotect the same. v

The hubs of the core bar gears or pinions 9 are provided with rectangular openings 21 to receive scuared rods 22, having forked ends 23 and forming core bar engaging prongs or members.. The forked ends 23 ex# tend into the adjacent ends of the core bars and straddle and engage transverse pins 24, whereby the core bars are detachably interlocked with the projecting 'prongs or mem- I vbers of the gears 9. The squared rods are slidable in the openings in the hubs of the gears, and they are adapted to be moved inwardly and outwardly' to engage them with and disengage them from' the transverse pins 24 of the core bars. Although the shank .or bar of the prongs is shown sanare. it will be readily understood that 'thev may be of any other polygonal shape,

and that any other suitable means may be employed for slidably interlocking the core bar engaging prongs or members with the gears. The form shown. however. has the advantage of simplicity, cheapness and strength.

The gear 9 at one end of the series meshesl with a gear or pinion 25, keyed or otherwise secured to a short horizontal shaft 26, which 1s journaled in opposite bearing recesses 27 and 28 of the spaced pedestals and the cap. The shaft projects beyond-the outer pedestal and has a large gear 29, keyed or otherwise secured to it. The large gear 29 meshes with a pinion 30 of an operating shaft 31, which 1s journaled .in a suitable bearing 32 of' a bracket 33, mounted upon the cap 14. The

bearing bracket is flanged and is provided at the bottom with a recess 34 to receive-the side of the device,

vthe core bars located beyond the same,

arched portion of the 35, or other suitable fastening devices. 'The pinion 30 is keyed, or otherwise secured to the outen end of the operating shaft, whlch is provided at its inner end wlth a crank 36, adapted to be rotated for operating the core bar turnin device. y

In practlce the skilly, which` is thrown onto the core bars by hand, is contained 1n a trough, or other suitable receptacle at one andthe crank handle is located at the inner side in order that the operator may be in a convenient position to see the core bars, which by their rotation are thoroughly exposed so that the coating may be easily, quickly and thoroughly applied. When the gearing is operated,

'each of the suppo-rted core bars is rotated in c'ore bars rotate The individual couplings for connecting the core bars with the actuating gears enables the core bars to be readily connected with the gearing, and to be easily and quickly placed on and removed from the device. The gearlng 1s adapted to impart a continuous rotary motion to the core bars, and it will also enable the core bars to be turned back and forth, so that any portion of their surfaces maybe maintained in an exposed position to receive the material.
